STBone - BeagleBone form-factor STM32F427 board

STBone Prototype

What is it?

STBone is a small (3.4" x 2.15" - standard BeagleBone dimensions) board with
an STM32F427 MCU. Designed to support many BeagleBone capes via the standard P8/P9
connectors, it provides the following features:

Motivation

This board was conceived as a simplified, low-cost stand-in for the Beaglebone
which would support many of the same I/O interfaces in a non-linux embedded
context. It has sufficient I/O resources to interoperate with many existing
Beaglebone Capes.
